SINUS PENTA
PROGRAMMING GUIDE

4.12. Fire Mode
When the digital input programmed as FIRE MODE is activated, all the protecting functions of the drive are ignored, so
that no alarm trips when the drive is operating.
CAUTION
The Fire Mode function must be used only when it is strictly necessary, such as in
fire pumps, to protect human lives.
This function must never be used to prevent alarms from tripping in domestic or
industrial applications.
NOTE
To activate the parameters relating to the Fire Mode, enter the Password in the PRODUCT
MENU.
This Password is provided by Elettronica Santerno’s Service Department. The drive Serial
Number is required (see the Serial Number parameter in the PRODUCT MENU).
The following parameters can be accessed only after entering the Password enabling the Fire Mode:
